Patented Sept. 5, 1944 LIPSTICK CONTAINER Willis H. Machin, Middlebury,Conn., assignor to Scovill Manufacturing Company, Waterbury, Conn., acorporation of Connecticut Application March 21, 1940, Serial No.325,195

(Cl. 20G-56) 4 Claims.

This invention relates to holders of the type in common use today forholding a lipstick. The invention is particularly concerned withso-called swivel lipstick containers which are characterized by means,operable in response to relative -rotary motion between parts, to propela lipstick material, to project it from the confines of the holder body,or to retract it after such projection.

It is among the general objects of the inenvtion to provide a novel,simple and improved construction especially designed to facilitatemanufacturing economy while insuring permanency and rigidity of theassembled parts.

A further object of the invention is to provide in a lipstick holder ofthe type herein referred to, an operating member joined to itsassociated parts in a novel, simple and efficient manner eX- cluding thenecessity of the use of solder or additional rivets or threaded elementsand which thus lends itself to smoothness andgrace of exteriorappearance. This object is also coupled With a further object which isto provide an operating. cap which encloses a portion of the side of theholder body providing an improved gripping area for the cap, whilepermitting .the contourof the cap to be designed to blend into theconfiguration ofY the assembly, thus to enhance its attractiveness ofappearance.

More specific objects will become apparent from a consideration of thefollowing specification.

taken in connection with the accompanying drawing Vin which:

Figure 1 is a View partly in section of one form of the inventionillustrating the cap as detached from the body;

Figure 2 is a transverse section through that form of the inventionshown in Figure 1;

Figure 3 is a detail section showing certain parts in the course ofassembly;

Figure 4 is a fragmentary section of a modified form of the invention,the parts being shownV prior to completed assembly; and

Figure 5 is a detail fragmentary section of that form of the inventionshown in Figure 4 with the parts fully assembled.

The invention is primarilyconcerned vwith the structure of the internaloperating sleeve and the external operating member or cap and with amethod for assembling them together Yinfan economical manner whichinsures rigidity and permanency of their union. The invention maywhereby, as a result of the application of force, the teeth of the headwill bite into the material of the shoulder causing the parts to unitewith a permanent rigid connection. In the modified form of theinvention, the union is further facilitated by the provision of aninverted cup, the edges of which are tapered outwardly. Upon forcing thehead into the cap, the edges of the cup act to further provide apressure for uniting the parts and for maintaining them permanently andrigidly in their united relation.

A feature of the invention is the arrangement of the operating cap asreceiving and enclosing the end of the body of the holder. The method ofassembly permits a smooth exterior for the cap and its extension up thesides of theY body not only lends grace of contour to the assembly butprovides ample gripping area for the cap, thus providing for ease ofmanipulation.

Referring now to the drawing, the lipstick material s indicated by thenumeral Ill, as is conventional in such devicesthe material is mountedin a carrier cup I I. The cup I I is slidably mounted in the operatingsleeve I2 which is provided With an elongated slot I3 through whichextends the head I4 of a pin I5 carried by the cup II. The pin extendsinto the cup to assist it in securing the lipstick material thereinwhile the external head I4 of the pin extends through the slot I3 andinto a helix I5 formed by a relatively stationary spiral Il which, inturn, is mounted Within an outer casing or body shell I8. Such structureis, in general, common to this art and does not in itself constitutepatentable novelty. In operation, it will be seen that When theoperating sleeve I2 is rotated with respect to the spiral II it will, inturn, rotate the' holder cup I I by virtue of the extension of the headI4 of the pin I5 through the slot I3. Since the head I4 also extendsinto the helix I6 of the spiral I'I rotary motion of the pin will causethe pin-and cup to move up or down the helix to project or retract thelipstick material from the end of the shell I8.

In that form of the invention here sho-Wn, the sleeve I2 is of tubular,open ended construction,

a bead 20 is provided adjacent its upper end vthe use of force.

between the parts. the cap I9, is substituted by an inverted cap 30,

face although other forms of knurling are contemplated by the invention.

In that form of the invention shown in Figures 1 to 3, the lower end ofthe 'operating sleeve I2 is closed by a cap I9 seated within the head 22and precluding the admission of foreign matter to the lipstick chamberas well as reenforcing the side iianges of the head and preventinginward collapsing thereof during assembly. The entire assembly is closedat its lower end by an operating cap 24, the side walls of whichpreferably extend upwardly over the body sleeve I8 for a substantialdistance.

It will, of course, be obvious that a permanently rigid connection mustbe established and maintained between the cap 2d and the sleeve I2 inorder to lprovide for the rotation or the sleeve with the rotation ofthe cap. Heretofore in assemblies of this type, it has been usual tosolder or rivet the external operating member to the linternal operatingsleeve, other connecting means have also been Suggested but eachprovided a difliculty or a multiplication of parts which the presentstructure and method avoids.

The cap of the present invention is provided with an internal shoulder26 which reduces lthe :internal diameter of the bottom of the cap belowl.the external diameter of the knurled head 22.

The width of the shoulder 26 is at least in part determined by the depthof the knurling 23, since it is essential to the invention thatthe-internal diameter of the shoulder should not be less than the outerdiameter of the head 22 taken at the lbottom of the knurling and inpractice it is suggested that the internal diameter of the shoulder beapproximately equal to the external diameter of the head takenintermediate the base and crest of the serrations.

It will be seen that when the parts are partly assembled as in Figure 3the shoulder 26 is in the path of the knurling 23 and further entry of'the sleeve within the cap is precluded except by When force is appliedin the direction of the arrow in Figure 3 as by a cylindrical tool T,the knurlings bite into the shoulder -26 cutting or broaching themselvesinto a permanent rigid union with the cap. Such union is automaticallyestablished upon forcing the head to the bottom of the cap and solderingor other securing means is not required.

From the foregoing, it will be seen that the Ymethod of the presentinvention includes the `step of uniting a lipstick operating sleeve withan operating member by forcing the knurlings of one of said members intothe material of a shoulder of the other member whereby the knurlings cutfor themselves their own permanent seat in 1the shoulder.

Referring now to Figures 4 and 5, it will be seen that the invention maybe modified to provide a further assurance of positive engagement Inthis form of the invention,

suitable tool such as shown at T in Figure 3 and the walls of the cap 30are deformed to right materially assists in economy of manufacture.-will, of course, be understood that various changes andmodications andthe full use of equivalents maybe resorted to in the practice of theinvention lwithout departing from the spirit or scope Aof the appendedclaims.

of a cap 35 preferably including a decorative reenforcing band 36 whichsurrounds its open end and provides a grip to assist in removing the capfrom the body shell I8. It will be noted that the cap is adapted toextend over the shell I8 and to the upper edge of the operating cap 25thus providing a symmetry of design when in position. VIn aconsideration of this invention, it will be vseen that the presentstructure avoids the use of any turned or screw machine parts. Thestructure and method of assembly permit all parts to be formed of sheetor tube material by simple drawing, rolling or spinning operations whichIt Iclaim: r1.
